Circulating Tumor DNA as a Cancer Biomarker: An Overview of Biological Features and Factors That may Impact on ctDNA Analysis

open access: yesFrontiers in Oncology, 2022
Cancer cells release nucleic acids, freely or associated with other structures such as vesicles into body fluids, including blood. Among these nucleic acids, circulating tumor DNA (ctDNA) has emerged as a minimally invasive biomarker for tumor molecular ...

Prediction of plasma ctDNA fraction and prognostic implications of liquid biopsy in advanced prostate cancer

open access: yesNature Communications
No consensus strategies exist for prognosticating metastatic castration-resistant prostate cancer (mCRPC). Circulating tumor DNA fraction (ctDNA%) is increasingly reported by commercial and laboratory tests but its utility for risk stratification is ...

Tracking early lung cancer metastatic dissemination in TRACERx using ctDNA

open access: yesNature, 2023
Measurements of subclonal expansion of ctDNA in the plasma before surgery may enable the prediction of future metastatic subclones, offering the possibility for early intervention in patients with non-small-cell lung cancer. Circulating tumour DNA (ctDNA)

The Role of ctDNA in Gastric Cancer

open access: yesCancers, 2022
Circulating tumour DNA (ctDNA) has potential applications in gastric cancer (GC) with respect to screening, the detection of minimal residual disease (MRD) following curative surgery, and in the advanced disease setting for treatment decision making and therapeutic monitoring. It can provide a less invasive and convenient method to capture the tumoural

Fragmentomic cfDNA Patterns in Noninvasive Prenatal Testing and Beyond

open access: yesJournal of Biomedicine and Translational Research, 2021
The release of fetoplacental cell-free DNA (cfDNA) into the maternal bloodstream opened up new avenues towards noninvasive prenatal testing (NIPT) for aneuploidies, hereditary DNA mutations and other pregnancy-related developmental disorders ...

ctDNA as a prognostic biomarker in resectable CLM: Systematic review and meta-analysis

open access: yesOpen Life Sciences, 2023
Cell-free circulating tumor DNA (ctDNA) is synthesized by tumor cells, including metastatic tumors, and circulates in the bloodstream. Evidence suggests that ctDNA is a potential predictive and prognostic biomarker for colorectal cancer (CRC), but its ...

Phase II study of apatinib in combination with oral vinorelbine in heavily pretreated HER2-negative metastatic breast cancer and clinical implications of monitoring ctDNA

open access: yesCancer Biology & Medicine, 2021
Objective: Apatinib is an oral TKI targeting VEGFR-2. Single-agent apatinib treatment has been shown to produce an objective response in patients with pretreated mBC. Oral vinorelbine also holds promise as a treatment of choice in patients with mBC. This

ctDNA response after pembrolizumab in non-small cell lung cancer: phase 2 adaptive trial results

open access: yesNature Network Boston, 2023
In the first stage of the BR.36 adaptive trial in patients with non-small cell lung cancer receiving anti-PD1 immunnotherapy, the primary endpoint of concordance between circulating tumor DNA (ctDNA) molecular response and RECIST response was met.
